Wind Energy Information. From offshore wind turbines to understanding wind turbulence, learn all about using the wind to our advantage. Also, wind testing buildings.
Aviation experts and zoologists have provided new insights into how gulls configure their wing shape -- known as wing morphing -- to stabilize their flight. The findings could be used to design more efficient flying vehicles, including soaring drones for farming or environmental monitoring.

Although many fixed-wing aircraft can withstand similar rapid pitch-up maneuvers, a vehicle subject to this dynamic stall process is not reliably controllable. Motivated by the lack of detailed understanding, researchers took a deep dive into the physics of dynamic stall so that it can be used beneficially and reliably by aircraft.

New research highlights a previously unexplored consequence of the global proliferation of wind energy facilities: a wake effect from upwind facilities that can reduce the energy production of their downwind neighbors.

Researchers have discovered that living plants are literally 'green' power source: they can generate, by a single leaf, more than 150 Volts, enough to simultaneously power 100 LED light bulbs. Researchers also showed that an 'hybrid tree' made of natural and artificial leaves can act as an innovative 'green' electrical generator converting wind into electricity.

Engineers have built and flown the first-ever plane with no moving parts. Instead of propellers or turbines, the light aircraft is powered by an 'ionic wind' -- a silent but mighty flow of ions that is produced aboard the plane, and that generates enough thrust to propel the plane over a sustained, steady flight.

With energy demands rising, researchers have completed an algorithm -- or approach -- to design more efficient wind farms, helping to generate more revenue for builders and more renewable energy for their customers.

The solar wind is not a calm summer breeze. Instead, it is a roiling, chaotic mess of turbulence and waves. There is a lot of energy stored in this turbulence, so scientists have long thought that it heats the solar wind. However, the heating expected from turbulence is not the heating observed. Scientists now have a new idea about what heats the solar wind, a theory called magnetic pumping.

Daily solar news updates, curated by hand, from hundreds of solar and renewable energy news sources.
The game-changer for clean energy (also known as Tesla – Elon Musk’s Company) is making waves in the industry of solar energy ever since they decided to make it their business. In true Elon Musk fashion, he decided to get Tesla involved in the niche of solar energy in 2016 when he let the world...

Hawaii is famously reliant on imported fossil fuels, for both electricity and transportation. But that’s changing rapidly as the state invests heavily in renewables. Two new bills are now pending in the Hawaii legislature that would codify the 100 percent renewables goal statewide, up from the current mandate of 40 percent by 2030. HB 623 would require...

In the ongoing wars over solar energy, one power company is consistently painted as the archetypal, mustache-twirling nemesis of clean electricity: Arizona Public Service. So you might be surprised to learn that this same company is about to become a big new producer of rooftop solar power. APS is an unlikely solar patron: In the...

So far, specific details are thin on the new battery designed for home use that Tesla’s announcing next week. But just based on what we do know, it’s a pretty big deal. The quest for a good battery that can store home-generated power is kind of like the holy grail for a renewable energy future. This...

Home solar batteries from Tesla Motors, which could upset utilities as we know them. Billion dollar solar bonds from SolarCity, backstopped by banking bigshots. Happy Earth Day! After being artificially suppressed for decades, renewable energy developments have accelerated, with excellent timing. Earth Day brought mounting news via Bloomberg that Tesla’s anticipated home solar batteries, hinted at in March...

This story is excerpted and adapted from Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future, due out May 19 from Ecco, an imprint of HarperCollins. On May 8, 2013, Tesla Motors shocked just about everyone by posting its first-ever quarterly profit, reporting higher-than-expected demand for its Model S electric sedan. That moment marked the beginning...
